Eleven planetary atmospheres are included for detailed study in this reference/text, four for the giant planets (Jupiter, Saturn, Uranus, and Neptune), four for the small bodies (Io, Titan, Triton, and Pluto), and three for the terrestrial planets (M

Relative rate experiments were used to measure ratios of chemical kinetics rate constants as a function of temperature for the reactions of OH with eight fluoroethers, including CF3OCF2CHF2, CF3OCF2CHFCF3, CHF2CF2OCHF2, CF3CHFCF2OCH2CF3, (CF3)2CHOCHF

For compounds with a single type of C H bond, it is shown that the Arrhenius parameters E / R and the A -factor for OH abstraction reactions can be reliably predicted from k (298 K), based on relationships derived from selected literature data. The p

The rates of reaction, Arrhenius preexponential factors, and activation energies of CH2FCH2F (HFC-152) and CH3CHF2 (HFC-152a) for the abstraction reaction with hydroxyl radical were measured by a relative rate method. Temperature ranges were 287−40

Relative rate experiments were used to measure the rate constant and temperature dependence of the reaction of OH radicals with 2-fluoropropane (HFC-281ea), using ethane, propane, and ethyl chloride as reference standards. Measurements were made usin

We propose a novel mechanism for isotopic exchange between CO_2 and O_3 via O(^1D) + CO_2 → CO_3^* followed by CO_3^* → CO_2 + O(^3P). A one-dimensional model calculation shows that this mechanism can account for the enrichment in ^(18)O in the s

Relative rate experiments were used to measure ratios of chemical kinetics rate constants as a function of temperature for the reactions of OH with isobutane, isopentane, 2-methylpentane, 3-methylpentane, 2,3-dimethylbutane, 2,3-dimethylpentane, 2,4-

Determination of accurate rate constants for OH abstraction is of great importance for the calculation of lifetimes for HCFCs and their impact on the atmosphere. For HCFC-141b there has been some disagreement in the literature for absolute measuremen

Earth is the largest of the four terrestrial planets, three of which have substantial atmospheres. The astronomical and orbital parameters are summarized in table 9.1. Our planet has an obliquity of 23.5°, giving rise to well-known seasonal variatio

The presence of an atmosphere on a small planetary body the size of the Moon is surprising. Loss of material by escape would have depleted the atmosphere over the age of the solar system. Since these objects are not large enough to possess, or to sus
